Lennox Comfortsense 7000 Question

My new comfortsense 7000 thermostat has an error reading "HVAC Error Detected". My installer checked the L input and everything on the HP and furnace checked out fine. Installer was on hold with Lennox for almost an hour (sitting at my dining room table, so I witnessed it myself), but he still doesn't have an answer. So I thought I would be "pro" active and ask you guys if you have any idea as to what may be the cause of the error message. Could it have something to do with the outdoor sensor that is wired but not yet physically installed?
